Got stuck on CWM

Hey,
i rooted succesfully my wildfire s and installed clockworkmod 5.0.2.6
now i tried to install MIUIv4 but it got stuck @ 1/8 of the progressbar.
I removed and reinsert the battery and then it started the clockworkmod not the android.
i cant go back it return me to the main menu of the clockworkmod.
i forgot to backup so i cant restore.
tried couple of times to factory reset and wipe but it doesnt help.
